Lady Gaga talks about 'ARTPOP' app as more details are teased about 'Applause'

Writing on the social networking site, the 'Judas' beauty explained that it will be available to download for free: "The ARTPOP app is Free, available in App Stores on your device. You can purchase the music through the ARTPOP app once it's downloaded. Or you can purchase the album at the music store+download the free app separately at the app store."

Gaga added: "The APP is in essence, an interactive jewel case. - GAGA."

Earlier this week DJ White Shadow, who co-wrote and co-produced Gaga's impending new single 'Applause', told Rolling Stone magazine that the track has a 'toe-tapping' quality.

Meanwhile, Gaga returned to Twitter in the past few minutes and confirmed that her "single 'Applause' and its MUSIC VIDEO will BOTH debut on same day", which will be August 19.
